What is the Virtual Astronomical Observatory?

The Virtual Observatory (VO) is an international effort to bring a
large-scale electronic integration of astronomy data, tools, and
services to the global community. The Virtual Astronomical Observatory
(VAO) is the U.S. NSF- and NASA-funded VO effort that seeks to put
efficient astronomical tools in the hands of U.S. astronomers,
students, educators, and public outreach leaders. These tools will
make use of data collected by the most powerful telescopes in the
world.

The VAO education site is a partner of the U.S. Virtual Astronomical Observatory (VAO). The VAO
main site is at www.usvao.org.
